hiera_hash string key variable

[João Matos]

Hi 

i wanted to had the value to hiera_hash string key from a variable

something like:

$variable= specific

$newvariable = hiera_hash('data::hiera::$variable')

is this possible what's the correct syntax?

Thanks

I think you want to interpolate a value into the string that is the key
you are looking up. If so, you would do this:

$variable = 'specific'
$newvariable = hiera_hash("data::hiera::${variable}")


Note that if you are on a recent release you want to use the lookup()
function instead of hiera_hash function (and friends hiera, hiera_array,
etc).

Greetings João,

Do you have it inside double or single quotes? If it's in single quotes,
like your example, then it's only going to be literal. To get
interpolation you've got to use double quotes like Henrik had.

Then something else is wrong, impossible to say what
since "didnt work" does not say much.

I am absolutely positive the example I showed does what you wanted
"interpolates a value into the key you are looking up" - clearly I do
not know if the variable has the value you expect it to have, nor if
there is anything at all to look up at that key, and that it is a hash.
